Why is my Pygame sprite rotating like a collision box?
Right, so this is out of all the questions and bugs I have had in Python/Pygame, the strangest one to me. So I just learned how to rotate something in Pygame and it was working fine with everything else except this one sprite.

How can I keep the last animation frame with blit = True
